I had a renewal quote today for my car insurance due next month with the AA, who I had used and negotiated annually for a number of years and have over 10 years NCB. My wife had added one of my sons to the insurance last year when I was in hospital, so I had expected an increase (he has been driving for over 10 years and has a clean record) and costs had gone up generally. They quoted a whopping 52% increase with the existing underwriter. I had already been on the various comparision sites to get some quotes and the cheapest one was an increase of 5% (£22) on my current insurance. I then phoned the AA for a 'conversation' about an unacceptable renewal quote and I actually told them the best quote and that if they could get close to it I would stay. They intitially offered a revised figure with a 36% iincrease. I said I wasn't interested in anything like that figure. Within 10 minutes they had changed the underwriter to the AA themselves and lo and behold the increase was now just 7%. (£30). That was just £8 more than the lowest quote I had got, so I went with that revised figure with the AA. Decent result for an hours work.
